UNODC and illicit crop monitoring

UNODC works with the main drug-growing countries in the world - Colombia, Peru and the Plurinational State of Bolivia for coca, Afghanistan, the Lao People's Democratic Republic and Myanmar for opium and Morocco for cannabis - to monitor the extent and evolution of illicit crops.

The crop survey data helps Governments in their policy development and in planning how to tackle the illicit crops. The monitoring systems supported by UNODC are tailored to the national contexts and emphasize training and development of local expertise.

The direct participation of UNODC in the national monitoring systems ensures transparency in the surveys and gives additional credibility to the results.
